硬件可靠性設計

電源的抗干擾設計

據工程(cheng)統(tong)計(ji)數據分(fen)析(xi)，電(dian)(dian)力儀表系統(tong)70%的(de)(de)干(gan)(gan)擾都是通過(guo)電(dian)(dian)源(yuan)(yuan)耦合進入系統(tong)的(de)(de)。因此，電(dian)(dian)源(yuan)(yuan)供電(dian)(dian)質量的(de)(de)提高對整個系統(tong)的(de)(de)可(ke)靠運行有著十分(fen)重(zhong)要的(de)(de)意義。由于系統(tong)的(de)(de)電(dian)(dian)源(yuan)(yuan)一般都是由市電(dian)(dian)轉(zhuan)換得到，所以(yi)(yi)電(dian)(dian)源(yuan)(yuan)部(bu)分(fen)的(de)(de)抗干(gan)(gan)擾設(she)計(ji)主(zhu)要集(ji)中(zhong)在電(dian)(dian)源(yuan)(yuan)輸入端(duan)口(kou)的(de)(de)濾波和瞬(shun)態干(gan)(gan)擾的(de)(de)抑制方面。圖1是電(dian)(dian)源(yuan)(yuan)抗干(gan)(gan)擾的(de)(de)一個典型設(she)計(ji)，其中(zhong)，RV1為熱敏(min)電(dian)(dian)阻，VZ1為壓敏(min)電(dian)(dian)阻，LA1為共模扼流圈。該電(dian)(dian)路可(ke)以(yi)(yi)有效抑制浪涌和群脈沖(chong)干(gan)(gan)擾。
